I added automatic image resize so that it can run on really large images in a timely manner. I also fixed up the command line version so it uses argparse and has some prettier output.

Passing a BytesIO object would be considered an instance of IOBase and therefore would not open it as an image.

Now, it will use Image.open on both strings and IOBase objects, but will accept PIL.Image objects as well in the else clause.

make image a thumbnail first for speed, speedup increases with image resolution (since we're converting to approximately constant time); 10x speedup on the small test images, 30x+ on larger images

Hi! I added structured output for results instead just call inspect(). However, It takes additional requirement colorama for colored output. It looks like

n = Nude('./nude.rb/spec/images/damita.jpg')
n.parse()
n.show()

With this extension nude.py can be run as a script too:

$ ./nude.py 
Usage: ./nude.py <image>

$ ./nude.py examples/images/damita.jpg
False
examples/images/damita.jpg: False #<__main__.Nude:0x2583550...

Performance is kind of random. A 1.9 MiB image of my cat takes about 2 minutes to process (which is really unusable in the context of a web server handling POST data). I profiled this run:

This is sorted by total time.

• _add_merge is called a lot, and also takes a lot of time overall, not in itself
• Calls to copy are expensive, somewhat expected; would have to figure out a way to avoid copy calls
• _classify_skin should be converted to C if possible?

 ERROR: Failed building wheel for nudepy

I was testing this script for some of my system use. When testing this code it gave me FALSE NEGATIVE on a full nude image. I can email you that image if you want to test, though I ca't upload it here because that is complete nude. Need help please have a look. Thanks for your time.

I'm looking at the _classify_skin method. (https://github.com/hhatto/nude.py/blob/master/nude.py#L283) I think there is a big waste of processing here since it returns rgb_classifier or norm_rgb_classifier or hsv_classifier or ycbcr_classifier. It seams useless to calculate the next classifier if the previous is True.

Traceback (most recent call last): File "/usr/local/bin/nudepy", line 9, in load_entry_point('nudepy==0.2', 'console_scripts', 'nudepy')() File "/usr/local/lib/python2.7/dist-packages/nudepy-0.2-py2.7.egg/nude.py", line 438, in main callback(_testfile(fname, resize=args.resize)) File "/usr/local/lib/python2.7/dist-packages/nudepy-0.2-py2.7.egg/nude.py", line 373, in _testfile n.parse() File "/usr/local/lib/python2.7/dist-packages/nudepy-0.2-py2.7.egg/nude.py", line 89, in parse pixels = self.image.load() File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 203, in load d = Image._getdecoder(self.mode, d, a, self.decoderconfig) File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 420, in _getdecoder raise IOError("decoder %s not available" % decoder_name) IOError: decoder zip not available

I cloned the project and ran the tests immediately and got "True" for damita2.jpg from the examples. I will investigate to see what causes this.

I currently want to integrate nudepy with one of my IRC Bot. (Some friends of me sends NSFW pics and people should be warned that it's NSFW) The fact is that I don't want to write the image on disk before analyzing it. Using requests, I can store the whole image in a BytesIO (or StringIO for python 2) in RAM instead of on disk. Is there a workaround to work with in RAM files ?
